A semiconductor junction diode, we can say that: a) The diode is composed of two types of crystal, one positive side (Anode) and the other P-type (Cathode) side, allowing the flow of charge from N to P. b) It is an electronic component that has two terminals, the Anode (with material of type N - Electrons) and Cathode (with material of type P - Gaps), which allows the flow of charge from P to N. c) It is the union of a P-type crystal and an N-type crystal, thus creating a PN junction, thus creating a simple solid-state device, the junction semiconductor diode. d) At a temperature of 25 degrees Celsius, the depletion barrier has a potential barrier, which for silicon is 0.7 volts and for germanium it is 0.3 volts. e) None of the above options is correct.

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.
